Chapter 22 DP512 Port Integration Module (S12XDP512PIMV2)
22.3.2.53 Port H Interrupt Flag Register (PIFH)
Read: Anytime.
Write: Anytime.
Each flag is set by an active edge on the associated input pin. This could be a rising or a falling edge based
on the state of the PPSH register. To clear this flag, write logic level “1” to the corresponding bit in the
PIFH register. Writing a “0” has no effect.
